Firefox: Mozilla's updated Firefox's address bar with an add-on that improves history searching, as well as adds a bunch of custom search engines to help you search by subject—like books, maps, movies or music.

Firefox's AwesomeBar has always gone above and beyond the call of duty, but Awesomebar HD adds a few cool new features for search-hungry Firefox users. The first thing they've done is improved history searching: now, Firefox pays attention to how often you visit and re-visit certain pages, so when you type in the name of a previously visited page, it can intelligently order the results in a way that gets you there quickest.

In addition, you don't need to go out of your way to create custom search engines for searching, say, Amazon.com, Google Maps, or your other favorite web sites. Firefox includes a bunch of these in Awesomebar HD, and actually puts them right in your address bar for quick access. You can either click on them and search, or type in something like music: britney spears to search Amazon.

Obviously, you can still create your custom search engines the old-fashioned way, too—this way just gives you another way to organize them and search them, especially if you're more of a mouse user, or if you know a less keyboard-savvy individual that could benefit from more precise searching. I'd love to see this have more options for more customization, but it is still in the experimental stages—so we can hope.

You don't even need to restart Firefox when you install it (O happy day!), so if you're curious, there's no reason not to give it a quick shot now. Check out the video above to see it in action, and hit the link below to install it.
